The European Union has added all airlines from Mozambique to a blacklist which prohibits operations within Europe.

In the 17th update of the EU’s “no-fly” list, released Tuesday, all air carriers certified in Mozambique were banned from flying into the EU because of “significant safety deficiencies” uncovered by aviation experts working in the region.

The new list, updated for the first time since November 2010, bans a total of 269 carriers from operations within Europe, hailing from 21 states around the world which are believed to have significant safety problems.
